224A Series Universal Product Line Cast Iron Internal Gear Pumps
The Universal Product Line 224A Series has the broadest range of sealing options of all pumps built by Viking.
The stuffing box on all sizes accepts packing, numerous component single mechanical seals, or a wide variety of cartridge seals. 224A Series Universal Product Line is Viking Pump’s most versatile line of internal gear pumps due to the availability of many design and material options.
• For demanding applications like asphalt and bitumen, our internal gear pumps offer high-temperature capability, abrasion resistance, and precise flow control—ideal for maintaining viscosity and preventing solidification during transfer or blending.
• Axial rotor thrust is controlled by double row ball bearing or tapered roller bearings; bushings provided a secondary point of radial shaft support.
• Rotatable bearing housing provides easy rotor end clearance adjustment to compensate for viscosity or wear.
• Numerous material options are available for bushings, idler pins, shafts, rotors, idlers and elastomers.
• Gear and pump geometry has been optimized based on more than 100 years of experience.
• Footed cast iron bracket provides rigid mounting to help maintain alignment, which extends seal and bearing life
• Can use direct drive, gear reducer or gearmotor drive, or belt-drive.
224A Series™
• Series designed with an enlarged bearing housing. Used in conjunction with a spacer coupling permits easy cartridge seal or O-Pro® seal installation and removal in place without removing the head and rotor/shaft.
• Seal options include packing, O-Pro® Barrier seal, single component seals, cartridge lip seals and cartridge single and double mechanical seals. Various seal flush plans are available.
